背景信息

**Background of MTDH Recombinant Protein**

Metadherin (MTDH), also known as astrocyte elevated gene-1 (AEG-1), is a multifunctional oncoprotein implicated in diverse pathological processes, including cancer progression, viral replication, and neurodevelopmental disorders. Initially identified in primary human fetal astrocytes stimulated by HIV-1 or tumor necrosis factor-alpha (TNF-α), MTDH gained prominence due to its overexpression in numerous cancers, such as breast, liver, and prostate cancer, where it correlates with tumor aggressiveness, metastasis, and chemoresistance. Structurally, MTDH contains multiple functional domains that enable interactions with key signaling pathways, including NF-κB, PI3K/Akt, and Wnt/β-catenin, facilitating tumor cell survival, angiogenesis, and immune evasion.

Recombinant MTDH protein refers to the purified, biologically active form of MTDH produced via recombinant DNA technology, often expressed in bacterial (e.g., *E. coli*) or mammalian systems. This engineered protein retains the native structure and function of endogenous MTDH, making it a critical tool for *in vitro* and *in vivo* studies. Researchers utilize MTDH recombinant proteins to investigate its molecular mechanisms, develop targeted therapies, and screen inhibitory compounds. For instance, it aids in studying MTDH’s role in promoting epithelial-mesenchymal transition (EMT) or modulating drug transporter expression in cancer cells.

Beyond oncology, MTDH recombinant proteins are explored in virology (e.g., HIV-1 pathogenesis) and neuroscience, given its links to neuroinflammation and neurodegenerative diseases. Its versatility underscores its importance in both basic research and translational applications, offering insights into disease mechanisms and therapeutic targeting. However, challenges remain in optimizing its stability and specificity for clinical use. Overall, MTDH recombinant protein serves as a vital reagent bridging molecular understanding to potential diagnostic and therapeutic innovations.
